### 常见监控问题

1. **指标丢失**

   - 检查收集器配置
   - 验证网络连接
   - 检查存储空间

2. **警报不触发**

   - 验证警报规则语法
   - 检查通知配置
   - 测试通知渠道

3. **仪表板加载缓慢**
   - 优化查询时间范围
   - 增加数据聚合
   - 检查数据库性能

## 最佳实践

1. **监控层次化**: 建立应用、基础设施和业务三层监控
2. **合理的警报**: 避免警报疲劳，设置合适的阈值
3. **数据保留**: 根据业务需求设置适当的数据保留期
4. **安全监控**: 监控安全相关的指标和事件
5. **持续优化**: 定期审查和优化监控配置
